UNLOADING-MAGHINE FOR RAILRGiDARS AND THE LIKE.

Application filed August '7, 1919.

T0 all `al1/icm t may concern Be it known that l, liviana F. WEBB, a citizen of the United States, residing at lernville, iu the ccuz'ity of Kern and State of California, have invei'ited new and useful Improvements in Unloading-lillachines for Railroad-Cars and the like, of which the following is a specification.

My object is to make an unloading machine for railroad cars and the like, and my invention consists of the novel features herein shown, described and claimed.

My present invention is an improvement upon my unloading machine for railroadV cars and the like, patented April 16, 1918, No. 1,263,170.

Figure 1 is a side elevation of an unloading machine for railroad cars and the like embodying the principles of my invention, the view being taken looking in the direction indicated by the arrow 1 in Figs. and 8.

Fig. 2 is a front elevation looking in the direction indicated by the arrows 2in Figs. 1 and F ig. 3 is a top plan view looking in the direction indicated by the arrows 3 in Figs. 1 and 2.

Fig. et is an enlarged fragmentary vertical sectional detail as on theV line 4.-4@ of Fig. 1. l

Fig. 5 a View analogous to lfig. .1 and showing the elevator suspended and the other operating mechanism lowered so that the unloading machine will not be top heavy in shifting into and out of position to work.

Fig. 6 is a fragmentary perspective showing the means for suspending the elevator as in Fig. 5.l y

Referring to the drawings in detail, the

gondola ears 1 and 2 have straight upper edges o and 4l, and the upper edges 3 and l of one car may be connected to the upper edges of an adgaccnt car by a bridge 5, so

that the upper edges of the cars form a continuous track upon which the unloading machine may run.

The truck frame 6 is mounted upon flanged wheels 7 and 8 and the wheels 7 and 8 run upon the upper edges 3 and l of the cars so as to support the frame 6. The end bars 6a of the tiiuck frame 6 are offset upwardly so as to pass over the brake wheels of the cars, and the wheels 7 and 8 have wide treads so to fit lthe cars of various widths. The screws 9,10, 11 and 12 are Specification of Letters Patent.

Patented Feb. 8, 1921i Serial No. 316,454.

rigidly fixed to floor flanges 13 and the floor flanges are fixed to the frame 6 so as to mount the screws in vertical parallel positions and in the form of a. rectangle.

Caps lei are placed upon the upper ends of the screws, braces 15 connect the caps together and guy rods 16 connect the `caps 14 to the corners of the frame 6 so as to hold the screws rigidly upright.

rlhe platform 17 rests upon bearing plates 18 at its corners, said platform being within the rectangle formed by the screws 9, 10, 11 and 12. The second bearing members 19 are nuts screw seated upon the screws 9, 10, 11 and 12 and have ball races in their upper faces, and bearing balls 20 t in these ball races, there being similar ball races in the lower faces of the bearings 18. F langes 21 extend downwardly from the bearings 18 into annular grooves in the upper faces of the bearing members 19 to hold the bearing" members 19 concentric to the loose holes 22 in the bearing members 18, so that the screws 9, 10, 11 and 12 will operate freely and loosely through the holes 22.

Flangcs 23 extend downwardly from the bearing members 18 around Y the bearing members 19, and pins 241 are screwed through the flanges 23 to engage the grooves 25 formed in the bearing members 19 to hold the bearing members 18 and 19 in operative relation to each other. Without the pins 24; the bearing members 18 may be raised oi' jarred sufficiently to displace the balls 20.

Bevel gears 26 are keyed to the hubs 27 extending downwardly from the bearing members 19. r1 shaft 28 is mounted in hangers 29 extending downwardly from the pla-tform 17, and bevel gears 39 and 31 are fixed upon the ends of the shaft 28 in mesh with the bevel gears 26 upon the screws 16 and 11. ln a like manner a shaft 32 is mounted in hangers extending downwardly `from the opposite side of the platform 17 and bevel f gears 33 and 341 are fixed upon the shaft 32 bearing members 19 upon the screws 9, lO,` 11 and 12 are operated simultaneously to raise or lower the platform 17. Obviously ilar arms tia and S5 are rigidly lined upon the opposite brace 15 atthe otherI end of the elevator, so that when it desired to suspend the elevatorl the platform 1T is raised until the shaft 56 is above the arms 82, 83, S4 andv S5. rlhe caps 57 are removed from the bearings to 'free the shaft 56 and sup-V porting bars S6 and 8? are placed under the ends of the sha ft 56 and on top of the arms 82, 83, Sel and 85, and then the platform l? removed thus leavingl the elevator suspended, as shown in Figs. 5 and 6. Thenvthe platform 1T is lowered to its lowermost position and the principal part of the weight of the machine, such as the engine platform, conveyor and so on is near the bottom of the machine.

.lhus l have produced an unloading machine for railroad cars and the like com- Vj )rising a carriage adapted to run upon the cars forwardly and baclrwardly, screws e2;- tcnding upwardly from the carriage, nuts upon the 4screws, bevel gears connected to the nuts, shafts and gears connecting the bevel gears of the nuts to operate simultaneously, a platform supported upon the nuts, an engine upon the platform, a connection between the engine and the train of gearing operating the supporting nuts to run the nuts up or down to raise or lower the platform, an elevator carried by the platform, a connection between the engine and the elevator for operating the elevator, and a connection leading from .the engine and adapted to be connected to an anchor for moving the machine forwardly or backwardly upon the car; so that an operator may stand upon the platform and raise or lower the platform, move the machine fon wardly or backwardly and operate the elevator; there being means for suspending the elevator so that the platform and other mechanism may be lowered for moving the machine; and there being rollers for supporting the machine to run sidewise.

Various changes may be made without departing from the spirit ofmy invention as claimed.
